please could you help me understand this is very simple terms.
1.0 x 10-2 = 1:100
(as in ten to the power of minus 2)
i do not understand what i need to do to get it into a ratio.
hi i do not understand how to get this as a ratio. 1.25 x 10-2Sv-1 = 1:80
(the - is a to the power of), how does that equal 1:80 what do i do step by step to get 1:80
please could you help i do not understand this.
acoustic impedance z
density p
speed of sound c
the speed of sound is 330 ms-1
density is 1.3 kg m-3
i need to know what to do with density and spped of sound to get acoustic impendance i know the answer is 0.00043 kg m -2 s-1 x10 but i do not know how to work out the formula?
